For example HCD schema requires it. I am not sure which bindings are used here, but anyway once they might require usb... Best regards, Krzysztof

Here we are talking about a device. In existing bindings related to USB device (or OTG as an OTG can be a host or a device) on several SOCs, we can find: - usb1: gadget@fffa4000 - usb_otg: usb@1c13000 - usb: usb@47400000 - udc: usb@13040000 - usb_otg_hs: usb_otg_hs@4a0ab000 So I will change to udc: usb@e0808000 Is that ok for you ? Regards, Herve

Add UDPHS (the USB High Speed Device Port controller) support. The UDPHS IP present in the lan966x SOC is the same as the one present in the SAMA5D3 SOC Signed-off-by: Herve Codina <herve.codina@bootlin.com> --- arch/arm/boot/dts/lan966x.dtsi | 11 +++++++++++ 1 file changed, 11 insertions(+)
